This is a sequel to Mayonaka wa ware no mono (also by Touchy) and as such, takes place not too long after the first game. In this game, we once again play as the main chara of the first Mayonaka, Ogata Seishirou, the man who consumed a demon lord and thus gained his powers and who is now trying to conquer the world, starting with Japan. In the path this game follows from the previous one, the "Special group" the government assembled to crush Ogata's organization was more or less obliterated - or so it was believed! Later information came into the hands of Ogata's organization, suggesting that the "Special Group" was not destroyed, rather lying low, but still remain in existence, led by their mysterious leader, "Ishtari". Setting his sights on some people with mystical abilities who could be members of the Special Group in hiding (or training), he sets out to pull up the tree - that is to say, the special group - with the roots this time. And woe to those who would dare to block his path...
